# #8 Physical Attack

**Definition:** Unauthorized physical interaction with or interference to hardware, facilities, media, interfaces (including **removable media**), or signals—via direct contact or exploitation of physical phenomena/emanations.

**Generic Vulnerability:** Physical accessibility of infrastructure and the exploitability of physical-layer properties (interfaces, wireless spectrum, emanations, environmental dependencies).

**Attacker’s View:** “I abuse the physical accessibility or properties of hardware, devices, and signals.”

**Developer’s View:** “I must assume physical access can mean compromise: secure key storage, encryption at rest, tamper evidence, secure failure modes, and exposure-minimizing designs.”

**Boundary Tests (normative):**

- If the physical step leads to FEC execution → **`#8 → #7`**.

**Topology:** Bridge (Physical → Cyber).
